New York solar generation set an all-time peak record April 17, generating 4,809 MW in the noon hour, NYISO told the Operating Committee on May 15.
Wind generation also nearly beat its all-time peak record of 2,309 MW set last December with 2,211 MW on April 16.
NYISO staff showed off a new format for their monthly operations reports at the meeting. The presentation featured infographics and graphs to show how the New York grid fared over the prior month.
A stakeholder asked whether the ISO would consider adding back the monthly spot market prices and price delta information to the report. Staff said they would consider it.
April proved to be a normal shoulder month this year. Load peaked at 18,836 MW on April 8, with a minimum load of 11,061 MW on April 20.
NYISO Prepared for Summer Demand
In a press release put out May 13, NYISO said 40,937 MW of resources will be available to meet an expected peak demand of 31,471 MW.
“While our summer assessment shows that we’ll be able to operate the grid reliably under forecasted conditions, we remain concerned about a variety of risk factors that could impact the grid,” Aaron Markham, NYISO vice president of operations, said in the release. “We will continue to coordinate with generators, utilities and other stakeholders as we monitor and respond to system conditions as they arise throughout the summer season.”
The reliability margin under baseline conditions is 997 MW. The ISO expects that under an extreme heat wave with an average daily temperature of 95 degrees Fahrenheit lasting three days or longer, it would be deficient 1,082 MW, declining to 2,768 MW with an average of 98 F. NYISO said it can dispatch up to 3,159 MW through emergency operating procedures in these extreme cases.
